Apps not available on this device

I just got my 950 and tried to install tunein radio - store informs me that the app is not compatible with my device.
It seems that the articles I have read and even the tunein website says that it should be available... is there a reason why certain W10 phones are incompatible with some apps? really going to miss tunein radio.
Are there any other major apps that will be lost with W10?
